water marks on concrete

(temecula, ca usa)

Q. How do you prevent water spots from sprinklers on stamped, stained and sealed concrete?

A. The water spots are from the minerals in the water. When the water dries it leaves behind the minerals that are in it (spots). If you could filter the water, that would help. If not the spots will continue to appear.

There is nothing you can put on the concrete that will prevent the spots from appearing. It's all about the water.
